Are you talking about the "Check engine" light or a light that's supposed to tell you it's time for an oil change?
If you mean the CEL: Don't know where you are (geographically) but in the US, stores like Autozone will tend to loan out scan tools. Most of the time, it's free (you might have to give them a 100% refundable deposit or something). You can check codes and reset the check engine light with such a tool.
For a maintenance light: Check your owners manual if you have it. There is most likely a simple "end user" procedure for resetting the light. If you don't have the owner's manual, try googling for "audi a4 service light reset". There are several results but it's not clear to me whether they are only applicable to certain years of the A4.
Hope this helps, and let us know what works for you!
EDIT: Looks like bramley computers beat me to it. This is one of the procedures listed online but one poster claimed it did not work with his/her 1998 A4 which I believe is the same generation as your 2000. Hopefully it works for you.

EDIT2: I found another possibility on wiki.answers.com:

Press and hold Service button, switch on the ignition. When the service message appears on screen - press 0.0 (odometer reset). That should reset your 'service!' message.

That's worth a try if you actually have a "Service" button.

If you do need a computer to reset it, it might be dealer-only or you might be able to do it with VAG-COM if you want to buy that setup or know somebody who has one. IIRC it's some software and a OBD2<->USB cable. It's Windows only I think.
